This invention relates to mechanism adapted to be controlled. by aninserted coin or the like, 'preferably through then medium of a switch,which is acted upon by the coin to close an electric circuit. v

The general object of provide an improved devic'eof this character, inwhich the coin closes the switch and holds it closed until the coin iscaused to release the switch bythe action of suitably timed mechanismoperated by an electric current passing through said switch. The deviceis so arranged that a plurality of coins may be -inserted at one timeand as soon as the opera- 154 tion initiated by one of these coins hasbeen completed, the 'next coin is in position to hold the switch closeduntil the completion'of the next operation. If more than a predeterminedy'number of -coins are inserted at one time, however, all coins inexcess of such number will be immediately returned, to the operatorthrough a supplemental outlet opening from the chute which leads to theswitch. The important features `of my invention and its mode ofoperation will be more specifically explained in connection with theaccompanying drawing, in which the single figure is a view partly inelevation and partly in section having a diagram of the wiring associatdtherewith. v As illustrated in the drawing, the device to which myKinvention relates comprises a chute 1 which is Vadaptedto receive anumber of coins 2. At one side of the chute near the lower end thereof,is a.v stop pin 3 against whicheach successive coin lodges. The oppositeside of the chute terminates some distance above the pin 3 as indicatedat 4.

An insulating block 5 is located near the side of the chute and hasabracket 6 secured thereto and extendingtoward the chute. An insulatingmember 7 is pivoted in the bracket A 6 asl indicated at, 8, and carriesa switch blade 9 which carries a contact 10 adapted to engage a fixedcontact 11 secured in the block 5. The switch 9, however, is adapted tobe held normally open by a' comparatively light spring 12 which bearsagainst the block 5. A spring "iinger-13fstronger than the-spring 12, issecured to the insulating member 7 and extends the invention is tonection 24. This timing me a train of speed reduction gearing 25 which8o downwardly adjacent the open side of the chute, terminating in acurved end 14 which is in opposed relation to the stop pin 3. Vhen thechute 1 is empty, the spring 12 holds the switch 9 open. 'The first coinin- 55 serted lodges between the pin 3 and the curved en d 14 olf-thespring inger and closes the switch against the comparatively lightresistance of the spring 1/2. One or more coins, however, up to thecapacity of the chute, are 6o not suiicient to overcome thelresistanceof the spring 13, so as to' pass the same, unless ejected by some forceother than gravity.4

Electric current is 'supplied by wires 15 and 16. When the switchl 9 isclosed a circuit 65 is completed from the wire 15 through wire 17,switch 9, contacts 10 and 11, wires 18 and 19, motor 2O and wire 21,which is connect'ed to the wire 16. 'Thus the motor 20 is driven aslong' as thezswitch 9 is closed. 70 Branch wires 22 and 23 lead rfromthe wires 18 and 21 respectively to a radio receiving set, phonograph,music' box, or 'other'electrically operated device, which Will beloperated only as long as the closed.

The motor 20 is adapted to drive a'timing mechanism by means of asuitable drive conchanism includes rotates a crank disc 26 in the'direction indicated by the arrow. This disc 26 is provided e with awrist pin 27 on which an ejector armV 28 is pivoted. The rearend of thisejector arm isconnected by suitable means, such las the spring 29, to afixed point 30, sothat as 1t is carried about the axis of the disc 26,the spring 29 has a tendency to'hold the tree end 31 of the ejector armtoward the chute 1. The side ofthe chute above the pin 3 is formed '3Uwith an opening 32 through' which the free end 31 of the ejector arm isprojected.

From the foregoing description, 'it will be seen 'that as a coin isinserted in the chute Y 1, itcloses the switch 9.and sets the motor 2095 in operation;` After 'a predetermined period of time, the operationof the motor rings the ejector arm 28 into the position shown' in thedrawing, in which it engages the lowermost coin 2 and forces the samepast the 100 switch 9 remains 75 I i silient portion engageable by thecoin, a fixed ystop 3 in opposition to the spring 13, thusV other coininthe chute,

places the ejected coin and retains the switch.

releasing thel switch 9 and allowing it to open under the influence ofspring 12 unless there is another coin in the chute. If there is anitimmediately re.-

in closed position, until the motor 2() and ejector army28 are movedthrough another cycle. This operation continues as long as there is acoinremaining in the chute.

Itwill be seen, therefore, that a number of vcoins may be placed in thechute simultaneously up to the limit of its capacity and the coincontrolled mechanism will operate automatically for a period of time inproportion to the number of coins inserted. If,

however, coins are inserted beyond the capacity of the chute, they willbe deiiccted from the chute through a branch opening 33 and will lbereturned to the operator.

vWhile I have shown and described in con` siderable' detail thepreferred form of lthe invention, it is to be understood that the samemay be. modified within the scope of the' through a predetermined cycleand) project it into the e'ect the coin t e switch.
